自动完成不起作用 - PHP - Mysql - jQuery

When I type anything in the text box it doesn't display anything. The search.php shows all the records if I hardcode $searchTerm='a';

Probably it is something in the jQuery I am missing.

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>test</title>
  <link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
  <script src="//code.jquery.com/jquery-1.10.2.js"></script>
  <script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
  <script>
  $(function() {
    $( "#skills" ).autocomplete({
      source: 'search.php'
    });
  });
  </script>
</head>
<body>

<div class="ui-widget">
  <label for="skills">skills: </label>
  <input id="skills">
</div>
</body>
</html>

MY PHP (search.php) page is:

 //get search term
        $searchTerm = $_GET['term'];

        //get matched data from skills table
        $query = $db->query("SELECT * FROM skills WHERE skill LIKE '%".$searchTerm."%' ORDER BY skill ASC");
        while ($row = $query->fetch_assoc()) {
            $data[] = $row['skill'];
        }

        //return json data
        echo json_encode($data);

Json

["A A EDU","A T Still","A.B.I. ","Aani", "Zane"]

    I can´t see the send params (data) to you server call.

    like this (but i haven´t right if this work):

    $(function() {
       $( "#skills" ).autocomplete({
          source: 'search.php',
          data: { 
             'term' : $('#skills').val()
          },
          type: "GET"
       });
    });
    

    I prefer use a plugin to do this, in the method AJAX is possible set the results to list in field. like this:

    $('#field_auto_complete').autocomplete({
        lookup: function (query, done) {
            $.ajax({
                url: "form.php",
                dataType: "json",
                data: { 
                        term     : query 
                },
                type: "GET", //you can change to POST if u need
                success: function( response ){
                    var result = {
                        suggestions: response.results
                    };
                    done(result);   
                },
                error: function(XMLHttpRequest, textStatus, errorThrown) { 
                    $.redirect('../error');
                }
            });
        },
        onSelect: function (suggestion) {
            id_ofselected = suggestion.data; //set a var with selected object
        }
    });
    

    In the Php Side u have a code like this:

    $digits = $_GET['term'];
    
    $query = $db->query(SELECT name AS `value`, id AS `data` 
              FROM table 
              WHERE name LIKE '$digits%'");
    
    while ($row = $query->fetch_assoc()) {
        $data[] = $row['skill'];
    }
    
    if(isset($data[0])){
        echo json_encode(array( 'results' => $cons ));
    }else{
        echo json_encode(array( 'results' => array());  
    }
    

    I use Autocomplete Jquery plugin. See [a link] (https://github.com/devbridge/jQuery-Autocomplete)!

    {
        source: function( request, response ) {
          $.getJSON( "search.php", {
            term: extractLast( request.term )
          }, response );
        }
